1. Product Introduction of LED Tube Light Diffuser
We make custom-made extruded plastic led tube light diffuser. These diffusers are made of PC or PMMA material in C shape, D shape, U shape, L shape or other closed shape for LED tube light.
Our LED tube light diffusers are specifically designed for enclosed tube fixtures, providing uniform light distribution while eliminating LED hotspots. Unlike open-channel LED strip diffusers, these closed-profile diffusers offer 360-degree light coverage and superior dust/moisture protection for commercial and industrial LED tube lighting applications.

Light Transmission by Diffuser Type
Clear / Transparent (90-95%)
Maximum brightness output. Best for task lighting where visibility is priority. LED chips may be visible.
Frosted / Semi-Transparent (85-90%)
Balanced diffusion and output. Reduces hotspots while maintaining good brightness. Popular for commercial use.
Opal / Milky (65-85%)
Uniform soft illumination. Completely hides LED chips. Ideal for ambient lighting in offices and retail.
Microprismatic (85-92%)
Optical lens design with excellent diffusion AND high transmission. Premium solution for professional fixtures.

FAQ
Q: Can you extrude double color LED tube light diffuser?
A: Yes, we can extrude two colors LED tube light diffuser or three colors LED tube light diffuser using our co-extrusion technology. This is ideal for diffusers requiring UV-protective layers or decorative color combinations.
Q: What is the light transmission rate of your LED tube diffusers?
A: Our LED tube light diffusers offer light transmission from 80% to 90%, depending on the diffuser type. Clear diffusers achieve 90-95%, frosted 85-90%, and opal/milky 65-85%. We can customize transmission rates based on your lighting requirements.
Q: What is the difference between polycarbonate and acrylic LED diffusers?
A: Polycarbonate (PC) offers superior impact resistance (250x glass) and UL94 V-0 flame rating, making it ideal for industrial and safety-critical applications. Acrylic (PMMA) provides slightly higher optical clarity (92-95% transmission) and natural UV stability, better suited for decorative and retail applications where aesthetics are priority.
Q: What certifications do your LED diffusers meet?
A: Our materials comply with RoHS, REACH environmental regulations. Polycarbonate diffusers can achieve UL94 V-0 flame rating. We can provide material test reports and certificates upon request. SGS testing available for specific requirements.
